The former chief executive of US regulator NASD, who retired in August, has taken up a position as senior adviser to a New York-based investment banking advisory firm.

Glauber spent six years as chairman and chief executive at NASD, overseeing the sale of its remaining $6.8m (€5.5m) stake in Nasdaq in July, and proposing improvements to make disclosure for mutual fund investors more concise and easier to understand.

He left NASD to return to teaching as a visiting professor at Harvard Law School. Glauber has also maintained a directors role at Moody’s, a quantitative credit risk products provider, and the government-backed mortgage provider Freddie Mac.

Before his career at the US regulator, Glauber spent three years as the undersecretary of the US Treasury for finance. He was formerly an executive director for the task force on market mechanisms, also known as the Brady Commission, which studied the 1987 stock market crash during the Reagan administration.

Peter J Solomon was founded in 1989. The firm offers companies strategic and financial advice on mergers and acquisitions, restructuring, as well as public and private financings. The firm recently advised on the sale of financial advisory boutique Duff & Phelps' credit rating business to ratings firm subsidiary Fitch IBCA. It also advised upscale retailer Barneys New York on its acquisition by retailer Jones Apparel Group.
